Question

1. How should one act toward people around him who knowingly steal from and lie to National Insurance, and steal from the public purse? Family, friends, etc.? Should one report them? Is it permitted? Appropriate? Advisable? Forbidden?
2. The Rabbi wrote that prayers do not help. (Only very rarely, if I remember correctly.) And the proof for this is the story of Nachshon Wachsman. 1. Why does the Rabbi think prayers are not answered? Meaning, is there no reason at all to pray that the bus will arrive at the station on time or that a business deal will go through, etc.? 2. What is the proof from the story of Nachshon Wachsman? Is the prayer of the Jewish people supposed to make him invulnerable? It is possible that the prayers really did save him, but that other things harmed him—for example, a car accident could naturally have happened to him in a way that would not contradict the prayer. If so, why could it not be that during the rescue something went wrong in a natural way? Why is this story proof that prayers do not help?
